Hi, thanx for your great work,

Compilation error: 'jsonVal' was not declared in this scope

any ideas?
Thanx!

Hello,
I use P1P2-udp on a hoval heating Pump... i use it only serial.
all works as expected.
i get the serial string and it is possible to write serial packets like 35400001 to turn dhw on etc.

the only problem is, if i connect the arduino on the P1P2 bus, the date stored in the main controller, resets to 2016. (the install year of the Pump). if i set the date to 2021... after a few seconds...2016. day and month are still correct.

if i use P1P2 monitor from arnold, the problem don´t extist.

You mention in your ReadMe

There is no external Modbus adapter for newer Altherma models, the official LAN adapter is very limited in functionality and as of today Daikin has no usable public API or cloud-based solution.

However I found the following two products. Would these solve this problem?

https://www.daikin.eu/en_us/products/RTD-W.html - For use with Altherma 3 HT models I believe
https://www.daikin.eu/en_us/products/RTD-LT-CA.html - For use with Altherma 3 LT models I believe
